Fitting and removing decat?

[welsh172]

I have a Prospeed decat on my car, well it's off my car the moment because i just had an MOT, what i want to know is, if i refit it myself can i just bolt it back on , or do i need some kind of grease on the join to make sure it's a tight fit? or am i making that up and i can just bold it on?

thanks

Use exhaust silicone on the joints and tighten the bolts up mate

Keep the gasket too.
